Belt Scale Accuracy in Heavy Industry

This article is about achieving real accuracy of 0.5–1.0% on belt scales with load cells in mining and cement industries. We examine simple factors that contribute most to error: belt tension, roller geometry and alignment, distance from loading point, flow uniformity. We add shop conditions: temperature, vibrations, humidity and material buildup. We explain which controller filters and functions really help: smoothing, auto-zero, tilt compensation, multi-point linearization. We compare calibration with material, standard weights/calibration chain and test chain — what's more accurate and when to do it. We provide a list of typical installation errors and how to quickly fix them. At the end — a checklist, 'condition → correction' table and simple calculations of savings from reducing error by 0.5–1.0%. We mention VKM-2T as an example, but it applies to any belt scales.
